18. Colorado Springs School District “ One of the primary focuses of the Performance Contract executed at Colorado Springs D11 was limiting facility demand at 4 sites to ensure that the schools could take advantage of the lower rate class. The real-time energy monitoring upgrades on-site allow the district energy manager to ensure this strategy is effectively executed. An added benefit of the technology is the ability to better diagnose malfunctioning equipment or maintenance needs in a proactive manner. ”
